Conditioning hair care compositions

Abstract

What is provided herein are conditioning hair care compositions comprising (a) a stabilized silicone product obtained by in situ polymerization of a water-soluble vinyl monomer, preferably vinylpyrrolidone, in the presence of discrete microdroplets of a silicone oil in water, (b) an emulsifiers, (c) a thickener, optionally, (d) a cationic surfactant, and the balance being (e) water.

What is claimed is: 
     
       1. A conditioning hair care composition comprising (a) about 0.5-10% by weight at 20% solids of a stabilized silicone product made by in situ polymerization of a water-soluble vinyl monomer which is vinylpyrrolidone or vinylpyrrolidone copolymerized with an acryl comonomer which is methacrylamidopropyl trimethylammonium chloride in the presence of microdroplets of 0.1 to 450 microns in diameters of a non-volatile silicone oil having a viscosity between about 100 and 100,000 cs, in water, wherein the weight ratio of the vinylpyrrolidone monomer to silicone oil in the polymerization mixture is about 95:5 to 5:95, respectively, on a weight basis,   (b) about 1-10% by weight of an emulsifying wax including glycerol stearate, and   (c) a thickener,   (d) up to 10% by weight of a cationic surfactant comprising a quaternary ammonium compound, and the balance being   (e) water.   
     
     
       2. A conditioning hair care composition according to claim 1 wherein said microdroplets are homogeneously distributed throughout the conditioning hair care composition 
     
     
       3. A conditioning hair care composition according to claim 1 wherein said weight ratio is about 90:10 to about 50:50. 
     
     
       4. A conditioning hair care composition according to claim 1 wherein said diameter of said microdroplets is about 1 to 100 microns, and a Brookfield viscosity of the stabilized silicone product is about 4,000 to 60,000 cps. 
     
     
       5. A conditioning hair care composition according to claim 2 wherein said silicone oil is a non-volatile polyalkyl siloxane, a polyaryl siloxane, a polyalkylaryl siloxane or a polyether siloxane. 
     
     
       6. A conditioning hair care composition according to claim 1 wherein (a) is obtained as about a 20-30% active dispersion. 
     
     
       7. A conditioner composition according to claim 1 comprising about 1-5% by weight at 20% solids of (a), about 2-7% by weight of (b) and (c), about 2-5% by weight of (d), the balance being (e) water. 
     
     
       8. A conditioner composition according to claim 1 wherein said thickener is stearyl alcohol, and said cationic surfactant is stearyl dimethylbenzyl ammonium chloride.
